| 目的 通过对广州市2003年重症急性呼吸综合征（SARS）疫情以及2020年新型冠状病毒肺炎（COVID-19）疫情病例流行病学、临床特征等关键指标对比分析，探讨2种疾病的流行特征、相关指标异同的原因，为疫情防控提供参考。方法 收集2种传染病在广州市流行期间确诊病例的一般情况、临床分类、活动史、接触史、家庭成员接触及发病情况，对2种疾病的时间特征、职业特征、年龄特征以及其他关键指标进行描述性分析，分析指标包括发病数、构成比（%）、均数、中位数、粗病死率等。结果 SARS纳入研究1 072例，报告重症353例，发生率为30.13%；报告死亡43例，病死率为4.01%；平均年龄38岁；医务人员病例占26.31%；从首次报告到持续零报间隔129 d。COVID-19纳入研究346例，报告重症病例58例，发生率为16.76%；报告死亡1例，病死率为0.29%；平均年龄46岁，未发生医务人员院感事件；从首次报告到持续零报间隔35 d。结论 广州市对COVID-19的防控效果优于SARS，应急响应的措施值得评价和总结。 |

| Objective By analyzing the epidemic characteristics and related indicators of SARS and COVID-19, to explore the reasons for the similarities and differences of the two epidemics, so as to provide reference for epidemic prevention and control. Methods The general situation, clinical classification, activity history, contact history, family members' contact and incidence of the two infectious diseases in Guangzhou were collected and used to analyze the time characteristics, occupational characteristics, age characteristics and other key indicators of the two diseases, including the number of cases, composition ratio (%), mean, median, crude mortality, etc. Results A total of 1 072 cases of SARS were included in the study. Three hundred and fifty three were severe cases with the incidence of 30.13%. Forty three cases of death were reported with a mortality rate of 4.01%. The average age was 46 years old, and 26.31% of the cases were medical staff. The interval time between first report to continuous zero reports was 129 days. As to COVID-19, a total of 346 cases were included. 58 of which were severe cases with the incidence of 16.67%. One case of death was reported with a mortality rate of 0.29%. The average age was 38 years old, and no hospital infection among medical staff was reported. The interval time between first report to continuous zero reports was 35 days. Conclusions The prevention and control strategies for COVID-19 were more effective compared to that of SARS, and the emergency response procedures were worth to be evaluated and summarized. |
